Located halfway between the bustling cities of Cairo and Alexandria in Wadi El-Natrun, the new plant is comprised of four 12 kilowatt wind turbines and a 50 kilowatt photovoltaic array, along with battery storage of around 500 kilowatt (KW) hours that allows farmers to pump water twenty fours hours a day, seven days a week.
Cleaner water pumps
Long reliant on increasingly dirty, expensive and unreliable diesel generators, Egyptian farmers are slowly being introduced to cleaner water-pumping solutions.
Karm Solar has been perfecting cost competitive solar-powered water pumps for some time and are currently working on a pilot project in an as-yet undisclosed location, but this is the first time that a hybrid solar and wind-powered pumping system has been introduced to the country.
With 2,000 plants and 2,000 megawatts under their belt already, juwi has a great deal of experience with delivering clean energy to both developed and undeveloped nations, but getting the Wadi El-Natrun plant underway was a formidable challenge.
All of the technical equipment, PV modules and inverters were shipped from Wörrstadt to Egypt in five freight containers, while the four wind turbines and battery storage system traveled separately from the Netherlands.
Working with an electronics company in Alexandria, juwi managed to assemble the pieces in just two weeks.
Diesel pump is obsolete
“Putting the system into operation after two weeks of hard work was an emotional moment,” said Fabian Jochen, Head of juwi’s Off-Grid section. “In the middle of the night, in the headlight of a pick-up truck, we activated the pumps for the very first time – and the water welted.”
“We haven’t just brought water into the desert, we have also transferred our know-how to people who can directly apply the knowledge,” explains Jochen’s colleague Norbert Borchert.
“Thanks to the new hybrid system the old diesel generator has become obsolete. That is good news for the environment and additionally saves fuel costs.”
While know-how has been transferred, the solar plant can be monitored via the internet from Germany using GSM remote monitoring.
“That way possible faults can be detected in real time and be sorted out immediately by local electricity companies,” according to a recent press release.
The University of Alexandria, which is conducting studies in the area to determine how to make the existing soil fit for agriculture, has put the project out for tender.
